About this game:
The Last Tinker is a joyous action adventure and definitely not a platformer, as there is no jump button. Koru, a boy from the slums of Colortown, must rise and stand against the Bleakness, a dark force intent on wiping out joy. Koru must use color and emotion to restore life to Colortown!

Do note its an unguaranteed key, I just know what it is because I already own it.
